WATER-BACK FOR STOVES.

' SPECIFICATION forming part of Letters'latent No.'782,358, datedFebruary 14, 1905.

Application flied December 10, 1903. Serial No. 184,534.

To all whom, it may concern: I

Be it known that I, DANIEL F. PRINTZ, a citizen of the United States,residing at Reading, in the county of Berks and State of'Pen nsylvania,have invented new and useful Improvements in Water-Backs for Stoves, ofwhich the following is a specification.

This invention relates to improvements in stoves in general, andparticularly to the means of securing the water-back in the fire-chamberin such a manner that the pipe connections therewith will not bedisturbed. Ordinarily the rocking of the grate-bars will jar theseparts, and this constant action will cause weak joints and consequentleakage. I prevent this occurrence by my present invention, the detailsof which are fully described in the following specification and clearlyillustrated in the accompanying drawings, in which Figure 1 shows aportionof the stove in vertical cross-section With my invention inposition. Fig. 2 is a detailed view of the waterback in perspective. I

The numeral 1 designates a water-back, the rear wall of which isprovided with a transverse longitudinal depression or groove 2,extending entirely across the same.

The numeral 3 indicates the stove-body provided with a transverselongitudinal rib 4, which is adapted to be seated in the groove 2 in therear wall of the water-back 1 when the same is in position. This rib andgroove are preferably made square in cross-section, as shown, thoughthey may be of any other desired form best suited for the purpose.

The numeral 5 designates the water-pipe connections in one end of thewater-back, and 6 indicates a rest or support secured to the wall of thestove-body, upon-which the waterback rests, said support being providedwith an upwardly-projecting lip along the front edge thereof, behindwhich the lower end of the water-back rests when the same is inposition.

The numeral 7 designates the approximate location of the grate-bars. A

When the parts are in position and the gratebars operated, thewater-back 1 will be held from any perceptible vertical movement bymeans of the groove 2 and rib 4 and any longitudinal movement by the lipon the front edge of the support 6. This will tend to preserve the pipeconnections, thus insuring them against leakage.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In a stove, the combination with the wall thereof, said wall beingprovided with a transverse longitudinal rib, and a support secured tothe wall below the rib; said support being provided with anupwardly-projecting lip along the front edge thereof of a water-back,the rear face thereof being provided with a transverse longitudinalgroove, the lower end of said water-back being adapted to rest upon thesupport and behind the lip in such a position that the rib 0n thestove-wall will enter the groove in the rear face of the water-back toprevent any vertical or longitudinal movement of the same.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses DANIEL F. PRINTZ. Witnesses:

ED. A. KELP, CAMERON E. S'rRAUss.
